Battery Replacement & Diagnostics

A slow crank or clicking noise signals failing cells. We provide rapid, evidence-based diagnostics in Compton to verify if you need a terminal service or a high-reserve replacement.

Testing performed before every replacement. No unnecessary sales.

Technical Protocol

  • Battery Load Testing: Confirming internal health and cell capacity.
  • Charging System Check: Verifying alternator 14V+ output levels.
  • Terminal Maintenance: Professional corrosion removal and sealant.
  • Intelligent Swaps: ECU Registration for modern Import platforms.

Who This Is For

  • Slow-Start Vehicles: Struggling ignition in the morning.
  • Short-Trip Drivers: Commuters who never reach full recharge cycles.
  • Modified Builds: High-draw underglow or audio setups.

Battery & Electrical FAQ

Modern BMW, Audi, and Mercedes vehicles use intelligent charging systems that increase alternator output as a battery ages. If a new battery isn't registered, the ECU will overcharge the new cells, drastically shortening their lifespan.
Not necessarily. Bright lights with no engine crank often point to a starter motor failure. A weak battery typically causes dimming lights or rapid clicking. We perform an amperage draw test to confirm the exact culprit.
Yes. If lighting kits are wired to a constant power source instead of a switched ignition source, they create a parasitic draw. We use fused relays to ensure accessories only pull power when the engine is active.
Absolutely. A failing alternator can overcharge and "boil" the battery acid or undercharge and leave the cells deep-cycled. We always perform a charging circuit audit before installing a new battery.
AGM (Absorbent Glass Mat) batteries are spill-proof, handle vibrations better, and charge faster. They are superior for performance builds or vehicles with high-draw electronics like winch systems or premium audio.
If the battery passes a load test, yes. However, heavy blue/white corrosion often signals acid leaking from the casing. We clean the terminals and apply a protective sealant, but we'll warn you if internal cell failure is imminent.
Temporarily. Disconnecting the battery wipes the ECU’s "Readiness Monitors." You will need to complete a drive cycle before the smog machine can test the vehicle. See our Smog Prep guide for details.
Yes. Low voltage causes computer modules to communicate incorrectly, often triggering "ghost codes" for sensors that aren't actually broken. Stabilizing the power supply frequently resolves these intermittent diagnostics issues.
Yes. While cold weather makes it harder to start, high heat is what actually kills the battery by evaporating internal fluids and accelerating plate corrosion. In Compton, most batteries have a 3-4 year reliable lifespan.
Not at ImportWorx. We use an OBD-II memory saver during every installation. This maintains a 12V supply to the ECU while the main battery is disconnected, preserving your settings, radio codes, and custom tuning maps.
